Answer

XMR Lotto is a gambling website using a crypto-currency called Monero (XMR) https://getmonero.org. It is run like a state lottery with a fixed number of entries for each game. Once all entries are sold a winner will be picked at random and that person will receive the entire jackpot.

Answer

Each game will have an initial random game seed of a nine digit number display above the game. Once all game tickets are purchased all of the ticket numbers will be published with a unique ID starting from one and going up to the total number of tickets sold. After the list has been published a "random seed" time of some time in the future will be announced and published on the same page. For example, if it is currently September 3, 2017 at 13:00 (UTC), it will be announced that a random seed will be chosen September 3, 2017 at 15:00 (UTC). At that time, the total number of lightning strikes for the five minute period of 15:00 to 15:05 will be obtained from blitzortung.org. The total number of lightning strikes in the world for that five minute period will be concatenated combined with the nine digit game seed. For example if the initial game seed is "123456789" and the total number of lightning strikes for the chosen five minute period is "26072" the winning seed will become "12345678926072". That winning seed will be used in the Mersenne Twister algorithm with a min of "one" and a max of the total number of entries. The resulting number generated by the algorithm will match the ID of the entry that wins.

Answer

The Mersenne Twister algorithm is a pseudorandom number generator. This means that it will generate a random number but it takes an initial "seed" value to compute the random number. This means that any time you use the same seed to run the algorithm it will always generate the same result. This is very important because it means that you can verify the winning number on your own by taking the random server generated game seed plus the number of lightning strikes for the published period and run the winning seed through the algorithm yourself.

If you want to test this out for your self visit the PHP Fiddle and use the winning seed in the previous FAQ with a min value of 1 and a max value of 100 and you'll always get the same result of 11. Here is the code you can test for yourself:

Enter the number of entries you would like to buy in the "Number of entries" box

The total amount of your bet will be displayed in the "Total due" box

Press the "Play" button

Once you have followed the above steps a message will tell you that we have received your entry successfully along with a payment address and a payment ID. Send the total amount due to the address displayed alonog with the payment ID that was provided to you.

NOTE: If you don't enter the correct payment ID displayed it will result in your funds being lost.
